USN-4689-2: Linux kernel vulnerabilities<\/p>\n
USN-4689-1 fixed vulnerabilities in the NVIDIA graphics drivers.
\nThis update provides the corresponding updates for the NVIDIA Linux
\nDKMS kernel modules.<\/p>\n
Original advisory details:<\/p>\n
It was discovered that the NVIDIA GPU display driver for the Linux kernel
\n contained a vulnerability that allowed user-mode clients to access legacy
\n privileged APIs. A local attacker could use this to cause a denial of
\n service or escalate privileges. (CVE-2021-1052)<\/p>\n
It was discovered that the NVIDIA GPU display driver for the Linux kernel
\n did not properly validate a pointer received from userspace in some
\n situations. A local attacker could use this to cause a denial of service.
